Public opinion may be driven by the elite, but to become PUBLIC opinion it must be held by a larger number than that. If there is enough public opinion in that way surely the contrary believ can not be said to be universal.
i.e. "Socialism is universaly believd to be wrong." If someone said that it would be untrue. Granted socialism is idiotic, provably failed, and not endorsed by most Americans(although we get closer every day), but it cannot be said to be universally believed to be wrong.. more's the pity.
